Get Column metadata of a dataset

Hey, i was wondering if there was a way of getting column's metadata of a given dataset such as:

- Number of columns
- Column's name
- Column's description

The metadata download of a dataset doesn't provide those info atm but we can easily see them on the dataset webpage.

Thanks

Start by locating the CLI code that downloads dataset metadata and tracing the response returned for a dataset. Compare that data with the fields shown on the dataset webpage, then determine how column count, names, and descriptions should be exposed in the downloaded metadata and verify the resulting output.
